1'0 @ZL w/wm it may con/cern:

Be it known that I, HUGH GLAss WATSON, manager, a subject of the King of Great Britain, residing at 16 Ooats street, Ooatbridge, Lanarkshire, Scotland, have invented certain new and useful Improvements in the Means for Manufacturing Aerated or Oarbonated Liquids, of which the following is a specification.

This invention relates to improvements in apparatus for the manufacture of aerated or carbonated liquids. p

Generally speaking, at present it is usual in aerated-water factories to first generate the gas and then collect it in a gas-holder, from which it passes to a mechanically-operated pump driven from a power-shaft or by hand.

4This pump forces the gas, along with the liquid, into a condenser under considerablepressure.` From-the'condenser the combined gas and liquid passes to the iilling-nozzles for filling the bottles or to a bottling-machine.

In some cases instead of generating the gas after passing from the pump to a spraying'- chamber is utilized to actuate the pump and is then exhausted from the pump to the bottling-machine and filled into the bottles. By

. adopting this system a great saving is edected, as no auxiliary power, suoli as an engine, is

required to drive the pump, and, lfurther, the whole apparatus can be'worked continuously with very little expense as compared with the present machines. v

The drawing shows in section the complete apparatus arranged so that the pump is driven` reducing-valve c, .so as to reduce the gas-pressure to the degree required, while the vessel a is provided with a ball-cock e or other device for regulating the iniiow of w ater from the pipe @Zand a water-gage f and a pressuregage g. The gas'is preferably allowed to enter at the bottom of the vessel a, so that it may bubble up vthrough the water and part of it become absorbed thereby.4 From this vessel i a flexible pipe 7L extends to the-top. of amixing-chamber a', and a flexible water-pipe j extends to the` bottom thereof.

chamber is arranged in connection with the] inlet to the pump, said inlet being provided with an automatically-acting inlet-valve Z. The pump m is also provided withy an' automatically-acting outlet-valve n, which communicates by a pipe o with a spraying or sat- The mixv ing-chamber is preferably arranged at such a urating chamber p, in which the gas and liq- A uid passes into a chamber q and then down y through a perforated plate or a rose or such like 1. From the spraying-chamber the gas and liquid passes by pipe s to a rose t, from whence it issues as a spray into the chamber u of the vessel a. This chamber isopen at its upper end, so as to be under the initial pressure of the gas in the vessel ci. The pressure gas and liquid passes from the chamber a by the pipe fu to the under side of the differential pump-piston w and owing to the fact that the piston w is largery than the -piston fw forces up said piston w' and compresses the gas and liquidin the pump-cylinder m. At the upstroke of the piston w the gas and liquid in the pump m is forced through the valve n into the spraying-chamber @,vw'hile -at thereturn stroke the gas and liquid from the mixing-chamber t' rushesV through the valve Z into the pump m.

The supply and exhaust of pressure liquid 4 to and from the pump-piston w of the large IOO -end of piston-rod 1l.

motor-cylinder m is controlled by an automatic valve arrangement, consisting of two valves m y, acted on by a spring fr', the one controlling the fluid-inlet from the pipe e and the other the exhaust-outlet to the pipe cf. Theoutlet-vabf'e 7/ has a piston 1/ in connection with it, and this piston may be acted on by means of pressure iiuid admitted at the proper time from a branch pipe ,e by the action of a reciprocating valve c', rigidly connected by rods 1 and 2 with piston-heads 3 and 4, playing in the elongated valve-chamber 5. The pipe s opens to this chamber between the valve e and the piston t and is never passed by either. The Valve is moved to the left to admit pressure iuid from pipe ,e through port 6 to the heavy valve-piston y/ and to the right to permit exhaust therefrom through pipe z. by fiuid in pipes z2 and z3, respectively, the first being connected with a small pressure-cylinder 5*, at the bottom of which is normally kept by spring pressure piston 7, with its rod 8 projecting downward through the top wall of the large pump-cylinder and into said cylinder and the second being likewise connected with a second similar compression-cylinder .25, in which the piston 9 is normally spring-supported at the top, with its rod l0 projecting centrally through'the flooring of the large cylinder' up into said cylinder. Near the end of the upstroke of the large pump-piston w it strikes piston-rod 8 and forces piston 7 upward, compressing the fluid in pressure-cylinder .e4 and pipe and forcing valve c to the left by the action of said fluid upon piston-head 4, thus opening the port 6 to pressure-pipe e and causing valve-piston 1/ to rise and project its rod 1l upward into valve-box l2, containing the above-mentioned valves fr and y. Valve a', with its valve-rod, is supported by spring ze from valve y, which is secured to the upper Therefore as valvepiston 3/ rises said rod lifts valve y from its seat, opening exhaust-passage e to the large pump-cylinder, and forces valve .fr into its seat, cutting off pressure from pipe e, and thereupon pump-pistons w w fall by their weight until piston w strikes piston-rod l() and forces piston 9 down into pressure-cylinder .25, compressing the inid therein and in pipe z3 and forcing piston-head 3 and valve 2 to the right to open port 6 to the exhaust, whereupon weighted piston y immediately falls, causing the closure of valve 1/ and releasing the spring-pressure on valve a' to such an extent that it is forced off its seat by the pressure in pipe e, opening said pipe again to the pump-cylinder m beneath piston fm, whereby the latter is immediately returned upon an upstroke. In order to keep the pipes z2 z3 normally under equal pressure and to replenish leakage, small ducts 13 14 are led through rods l and 2, piston-heads 3 and 4E, and valve to a port or ports through-rod 2 to the right of the valve, which ports are always in communication with branch pressure-pipe If so desired, the gas and liquid may be passed direct to the pu111p-cylindcr m without the intervention of the miXing-chamber.
